From downtown boutiques in Cheyenne to restaurants near the University of Wyoming in Laramie and doggie day cares in Casper, Wyoming businesses all share one common responsibility: collecting and remitting sales tax correctly. While Wyoming is often viewed as a low-tax state, its sales tax system still includes local option rates, filing rules, exemptions, and penalties that can trip up even experienced operators.
This guide breaks down Wyoming sales tax in plain English for brick-and-mortar retailers, restaurants, cafes, food trucks, online businesses, and more. You’ll learn how rates work, what’s taxable, how to register and file, and how automation tools like DAVO by Avalara can remove the administrative burden from your day-to-day operations.
What is the Wyoming sales tax?
Wyoming imposes a 4% state sales tax on the retail sale, lease, or rental of tangible personal property and certain services. Counties and municipalities may also impose local option sales taxes, which means the total rate varies by location.
| Location | State Rate | Local Rate | Combined Rate |
|---|---|---|---|
| Cheyenne | 4% | 2% | 6% |
| Casper | 4% | 2% | 6% |
| Teton County | 4% | 1% county + 2% special purpose | 7% |
Note: Local rates frequently change. Always verify the current, specific rate for your business address using the official Wyoming Excise Tax Division rate charts before collecting tax.
How to calculate Wyoming sales tax?
Wyoming sales tax is calculated by applying the combined state and local tax rate to the taxable portion of a sale.
Base formula:
Sale price × combined sales tax rate = sales tax due
Let’s say a retail store in Casper sells a jacket for $80. The total Casper sales tax rate is 6%.
$80 × 0.06 = $4.80 sales tax
Total charged to customer: $84.80
If your business operates in multiple Wyoming cities or counties, using the correct local rate for each transaction is essential. Charging the wrong rate can lead to underpayments, overpayments, and reconciliation issues during filing.
Using our reverse sales tax calculator
Many restaurants and food trucks display items using “tax-included” pricing. That’s where a reverse sales calculator can come in handy.
For example, imagine a food truck in Cheyenne sells a combo meal for $10 even, tax-included. Using a reverse sales tax calendar, the owner can enter the local sales tax rate to back out how much of that $10 is tax versus revenue. This helps ensure you remit the correct amount, even when prices are set with tax included.
Vendors that move between jurisdictions, like pop-up shops and food trucks, often have to deal with different local rates, sometimes daily.
What is subject to sales tax in Wyoming?
Wyoming taxes most sales of tangible personal property and select services. Common taxable items include:
- Clothing and footwear
- Furniture and home goods
- Electronics and appliances
- Digital products
- Computer hardware and software
- Prepared food and beverages
- Alcoholic beverages
- Tobacco and vaping products
- Retail merchandise sold in stores or pop-up locations
- Rentals of equipment and certain personal property
The Wyoming Excise Tax Division Vendor Manual provides detailed guidance on what sellers are required to collect tax on and how transactions should be reported.
Does Wyoming charge sales tax on services?
Wyoming does not broadly tax services, but several specific services are taxable. These generally include services that result in the fabrication, alteration, or repair of tangible personal property.
Examples of taxable services may include:
- Repair or maintenance of physical goods
- Vehicle detailing services
- Garages and service stations services
- Laundry, dry cleaning, and pressing
- Certain installation services
- Fabrication labor when tied to a taxable sale
- Lodging and accommodations
Because service taxability depends on how the service is performed and billed, businesses should review state guidance carefully or consult with a tax professional when services are part of their revenue mix.
Wyoming sales tax for remote sellers and marketplace facilitators
Wyoming enforces economic nexus laws for remote sellers and marketplace facilitators. This means a business can be required to collect Wyoming sales tax even without a physical presence in the state.
A remote seller or marketplace facilitator establishes economic nexus if, in the current or previous calendar year, they have:
- More than $100,000 in gross sales delivered to Wyoming, or
- 200 or more separate transactions delivered into Wyoming
Marketplace facilitators are generally responsible for collecting and remitting tax on behalf of marketplace sellers (third-party sellers) using their platform.
Brick-and-mortar Wyoming businesses should still be aware of these rules, especially if they also sell online or through third-party marketplaces.
Wyoming sales tax on food
Most (but not all) food sold at grocery stores is considered “for domestic home consumption,” which is tax-exempt.
Most prepared food that restaurants, cafes, food trucks, and concession stands sell in Wyoming is subject to sales tax. This includes meals sold for immediate consumption, beverages, and catering services.
Because local rates vary, food businesses operating in multiple locations face additional complexity. A food truck might collect 6% in Cheyenne one day and 5% in another county the next.
DAVO helps restaurants, cafes, and mobile food businesses automatically set aside sales tax from each transaction and remit it on time, even when operating across multiple jurisdictions with different tax rates.

What is exempt from sales tax in Wyoming?
Wyoming exempts certain transactions, purchases, and entities from sales tax collection. Common exemptions include:
- Sales for resale with a valid resale certificate
- Livestock, poultry, and their feed for marketing.
- Seeds, fertilizer, and bulbs planted on land.
- Sales to exempt organizations when proper documentation is provided
- Prescription medications and select medical equipment
- Textbooks
Exemptions must be properly documented. If documentation is missing or incomplete, the seller may still be liable for the tax. Wyoming’s Streamlined Sales Tax Project offers compliance documents, such as the Exemption Certificate.
How to manage tax-exempt sales in Wyoming?
Businesses making tax-exempt sales must collect valid exemption certificates from the buyer, report exempt sales, and retain documentation for their records. Remember these best practices:
- Verify certificates are fully completed before completing the sale
- Keep certificates on file for audit purposes
- Apply exemptions only to qualifying items
- Review certificates periodically for expiration or accuracy
Failure to manage exemptions correctly is a common audit issue for retailers and wholesalers alike.
Wyoming sales tax holiday
Wyoming does not currently offer a recurring statewide sales tax holiday.
How to register for a Wyoming sales tax license?
Any business required to collect Wyoming sales tax must complete the Wyoming Sales/Use Tax License Application (click “Regular Vendors”) before making taxable sales. There is a $60.00 nonrefundable licensing fee. You can submit an application through the Wyoming Internet Filing Service (WYIFS) portal. If you do not have a WYIFS account, create one.
When registering for a sales tax license, businesses should be prepared to provide:
- Legal business name and “doing business as”/DBA, if applicable
- Federal EIN or Social Security number
- Business address and mailing address
- Description of business activities
- Anticipated start date of taxable sales
- Estimated monthly taxable sales
Remote sellers and marketplace facilitators that meet Wyoming’s economic nexus threshold are also required to register.
You can also submit the application by mail; include a $60 application fee (checks or money orders only). Mail to:
Wyoming Department of Revenue
Excise Tax Division
122 W. 25th Street, Herschler Bldg.
Cheyenne, Wyoming 82002-0110
After submitting an application, most businesses receive their Wyoming sales tax account number within several business days, though processing times may vary.
How to file Wyoming sales tax?
There are two filing options:
Wyoming Internet Filing System (WYIFS)
Most businesses file Wyoming sales tax returns through the Department’s WYIFS online portal.
See the WYIFS Sales Tax Return Instructions for Vendors for step-by-step filing instructions with screenshots.
Paper filing
Paper filing is generally discouraged in favor of the ease and accuracy of WYIFS submissions.
Monthly and quarterly filers should use Return 41-1. Annual filers should use Return 42-1.
Submit completed paper returns and payments to:
Wyoming Department of Revenue
122 West 25th Street, Suite E301
Cheyenne, WY 82002
Remember, all retail businesses must still file a return even if no tax is due for a reporting period. File a zero return when applicable to avoid penalties.
The Wyoming Department of Revenue Vendor Manual provides official guidance for sellers.
How to pay Wyoming sales tax?
Wyoming accepts several payment methods for sales tax through the WYIFS portal, including:
- ACH debit/e-check
- Electronic funds transfer through approved banking systems
- Credit card payments through a third-party credit card processing company, Official Payments.
The department also accepts wire transfers and ACH credits, although not through the WYIFS system.
Paper checks may be accepted in limited cases; the Department encourages electronic payment and often requires it for larger taxpayers.
Note: You may choose to file electronically and still pay by check. In the WYIFS portal, you can print a voucher with your business’s identifying information. Attach the voucher to your payment when paying by check.
You could also make the tax payment process easier on yourself. DAVO automatically pays sales tax on your business’s behalf using funds already set aside. Less hassle, less worry, and less risk of missed deadlines.
Wyoming sales tax due dates
Once licensed, the Department assigns a filing form type and frequency, e.g., monthly, quarterly, or annually, depending on your reported tax volume. Returns are due on the last day of the month following the reporting period.
| Filing Frequency | Due Date |
|---|---|
| Monthly | On or before the last day of the month following the tax reporting period (e.g., Feb. 28, for the period ending Jan. 31) |
| Quarterly | On or before January 31, April 30, July 31, and October 31 |
| Annual | On or before January 31 of each calendar year |
Wyoming vendor discount
Wyoming rewards vendors who report and remit sales and use taxes on or before the 15th day of the month when the tax is due. Early filers can receive a vendor compensation credit of 1.95% of the tax due for the first $6,250 due in tax. The Department grants a credit of 1% of the amount of tax due for any amount exceeding $6,250. The total credit cap is $500.00 per filing period per vendor/owner.
Do you operate in other states? See where vendor discounts are available. DAVO returns this collection allowance to the business in full, which in many cases offsets the entire subscription cost.
What is the Wyoming sales tax late payment penalty?
Late-filed or late-paid Wyoming sales tax may result in:
- A penalty of up to 10% of the tax due
- An additional $25 penalty if not filed within the next 30 days
- 1% interest accruing monthly until paid in full
Consistent late filings can trigger audits or increased scrutiny.
